EDSM shows 4 different people having visited "Boelts XH-C C29-854", and it's not far from where the DW2 fleet is currently. I might have to swing over and look, but my time is limited for the next couple of days, so I'm sure someone will beat me there.
Happened to read this while playing and decided to see just how far away I was. 2 jumps. Huh. Well, rude not to take a peak then.
System map, not looking too hopeful...
There's only 1 class II GG in the system, this one (still not looking hopeful):
Nearly jumped at that point but figured it was worth an eyeball. Even then, nothing. Figured I'd flown that far, least I could do was fly around it. You never know.
Now I'm left wondering if I've dismissed others...
